Pioneer SA-9800

1 9 7 8 1978
1 9 8 0 1980

Less features, less weight and a more conventional enclosure than the previous SA-9900 monster but a huge leap in specs, bandwidth and s/n ratios...

And Fluorscan meters :-)

"Pioneer's super-linear Ring Emitter Transistors (RETs), used for power output in the Magni-Wide amps in conjunction with a unique biasing circuit, solve the distortion and power problems.

The Pioneer Vari-Bias circuit (PVB) causes the RETs to operate without switching or crossover, virtually as Class A power amps.

Like the smooth automatic transmission of a car, it ensures a supersmooth "ride" for the electrons of the audio signal.
